Marine KH Buffer Phosphate free 1kg

Phosphate free. As marine life needs a stable environment, our Marine KH Buffer raises carbonate hardness, locking the pH at around 8.4pH. It also helps to maintain high alkalinity, stopping pH fluctuations, creating pH stability and reducing stress on fish and corals.

Directions: 1 teaspoon by measure or 5g to 10 litres of water will raise carbonate hardness by approx. 12dkH or 214ppm and stabilise pH to around 8.2.
